acq::DeviceThis provides the basic interface to communicate with a digitizer card. Some example code:
#include "ACQ/Device.hh"
#include <iostream>
using namespace std;
int main(int argc, char** argv)
{
if (argc != 2) {
cout << "Usage: prog ip_addr_of_digitizer" << endl;
return 1;
}
acq::Device dev(argv[1]);
cout << "IP Address: " << dev.IPAddress() << endl;
cout << "Num sites: " << dev.NumSites() << endl;
for (size_t i=0; i<dev.NumSites(); i++ ) {
cout << " Site: " << i << ", Num channels: " << dev.NumChannels(i) << endl;
}
cout << "size of ADC word (bytes): " << dev.ReadoutSize() << endl;
cout << "Help output: " << endl << dev.SendCommand("help") << endl;
return 0;
}Readout is handled by pulling data from a TCP socket as fast as possible. This data is read out in buffer-size chunks and passed on to a function defined by the user. This can be seen in the following code:
#include "ACQ/Device.hh"
#include <iostream>
#include <chrono>
#include <thread>
using namespace std;
int main(int argc, char** argv)
{
if (argc != 2) {
cout << "Usage: prog ip_addr_of_digitizer" << endl;
return 1;
}
acq::Device dev(argv[1]);
cout << "IP Address: " << dev.IPAddress() << endl;
cout << "Num sites: " << dev.NumSites() << endl;
typedef int16_t readoutType; // 16-bit cards
//typedef int32_t readoutType; // 32-bit cards
dev.BeginReadout<readoutType>( [] (acq::Device::DevTempl<readoutType>::ptr_type ptr) {
// This function runs in a separate thread
cout << (*ptr)[0] << endl;
},
1024*1024 // Buffer size (in bytes)
);
// Wait for 2 s then call stop
std::this_thread::sleep_for(std::chrono::seconds(2));
dev.StopReadout();
return 0;
}
